Abstract
BACKGROUND AND AIM Growing body of evidence consistently link obesity and inflammation, Although the direction of the association is still unclear. We aimed to investigate longitudinal associations of body anthropometric, composition and fat distribution parameters with inflammatory markers and vice versa. METHOD AND RESULTS We used data from 2464 individuals of the SHIP-TREND cohort with a median follow-up of 7 years. Linear regression models adjusted for confounders were used to analyze associations of standardized body composition markers derived from classic anthropometry, bioelectrical impedance analysis (BIA) and magnetic resonance imaging (MRI) at baseline with changes in inflammatory markers (C-reactive protein (CRP), white blood cell (WBC), fibrinogen) and vice versa. Higher level of anthropometric markers at baseline were associated with an increase in the change of inflammatory markers. A 13.5 cm higher waist circumference (WC), 16.0 kg body weight and 7.76 % relative fat mass (FM) at baseline was associated with a change in CRP of 0.52 mg/L (95 % confidence interval [CI]: 0.29 to 0.74), 0.51 mg/L (95 % CI: 0.29; 0.74) and 0.58 mg/L (95 % CI: 0.34; 0.82) respectively. Absolute FM showed the strongest association with changes in serum fibrinogen levels (β for 8.69 kg higher FM: 0.07 g/L; 95 % CI: 0.05; 0.09). Baseline inflammatory markers were only associated with changes in hip circumference. CONCLUSION Our study indicates the importance of anthropometric, body composition and fat distribution markers as a risk factor for the development of inflammation. To prevent inflammatory-related complications, important is to take measures against the development of obesity.

Nutr Metab Cardiovasc Dis 2024; 34:642-650. [PMID: 38161120 DOI: 10.1016/j.numecd.2023.10.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 09/21/2023] [Accepted: 10/22/2023] [Indexed: 01/03/2024]
Abstract
BACKGROUND AND AIMS We investigated whether genetic predisposition, the Lifestyle Inflammation Score (LIS), or the Food-based Dietary Inflammatory Index (FDII) were associated with diabetes incidence and whether these factors interact. METHODS AND RESULTS The study was conducted using population-based cohort data derived from the Korean Genome and Epidemiology Study, which included 6568 people aged 40-69 years. Based on 25 genetic variants related to diabetes, genetic risk scores (GRSs) were determined and LISs and FDIIs were calculated and stratified into quartiles. We investigated the effects of gene-lifestyle interactions on the incident diabetes. The multivariate Cox proportional hazard model was used to generate hazard ratios with 95 % CIs. During the 16-year follow-up period, diabetes incidence was 13.6 per 1000 person-years. A dose-response association with diabetes was observed for both GRS and LIS quartiles but not for FDII quartiles. The GRS and LIS were also independently associated with diabetes incidence in a multivariate model. Compared to the bottom quartile, the top LIS quartile and the top GRS quartile had a 2.4-fold (95 % CI, 2.0-2.8) and a 1.4-fold (95 % CI, 1.2-1.7) higher diabetes risk, respectively. However, the FDII exhibited null association. When each genetic variant was evaluated, the top versus bottom LIS quartiles exhibited heterogeneous diabetes risks for rs560887 within G6PC2, rs7072268 within HK1, and rs837763 within CDT1; however, these differences were not statistically significant in multiple comparison. CONCLUSION Both GRS and LIS factors independently affect the incident diabetes, but their interaction effect showed insignificant association. Therefore, regardless of genetic susceptibility, more effort is needed to lower the risk for diabetes by improving lifestyle behaviors.

Abstract
BACKGROUND AND AIM The associations of body composition markers derived from different modalities with inflammatory markers are unclear. The aim of this study was to determine associations of the body composition markers from different modalities with inflammatory markers in a population-based study. METHODS AND RESULTS We analyzed data from 4048 participants (2081 women, 51.4%) aged 20-84 years. Linear regression models adjusted for confounding were used to analyze the association of classic anthropometry markers, absolute and relative fat mass, absolute fat-free mass (FFM), and body cell mass (BCM) assessed by bioelectrical impedance analysis, subcutaneous, visceral, and liver fat from magnetic resonance imaging (MRI), with markers of inflammation. We found positive associations of classic anthropometry markers, total body fat, subcutaneous, visceral, and liver fat, with all inflammatory markers. Waist circumference (WC) showed the strongest association with high-sensitivity C-reactive protein (hsCRP) (β: 1.39; 95% confidence interval [CI]: 1.22 to 1.56) and white blood cell (WBC) (0.39; 0.29 to 0.48), whereas visceral fat showed the strongest association with ferritin (41.9; 34.7 to 49.0). Relative body fat was strongly associated with hsCRP (1.39; 1.20 to 1.58), fibrinogen (0.29; 0.27 to 0.32), and WBC (0.35; 0.25 to 0.46). Conversely, we found inverse associations of body height, FFM, and BCM with hsCRP, fibrinogen, and WBC. CONCLUSIONS Our study indicates the importance of WC as an easily measured marker for early inflammation. MRI-assessed markers of central obesity seem to be most strongly related to ferritin.

BMC Pregnancy Childbirth 2022; 22:531. [PMID: 35768766 PMCID: PMC9245225 DOI: 10.1186/s12884-022-04849-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Accepted: 06/06/2022] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Obesity has been linked to systemic inflammation in population studies. OBJECTIVE To examine the associations of prepregnancy body mass index (pBMI) and total gestational weight gain (tGWG) with maternal prepartum low-grade inflammation (LGI) and clinically significant inflammation (CSI) defined by serum C-reactive protein (CRP) concentration. METHODS Five thousand four hundred seventy-six Chinese women with uncomplicated pregnancies and recorded data on pBMI and prepartum body weight were included in this study. Blood samples were drawn before delivery for high-sensitivity CRP assay. Inadequate, optimal, and excessive tGWG were defined using the Institute of Medicine's recommendation. Multivariable Poisson regressions were used to estimate relative risks (RRs) for having prepartum LGI and CSI (defined as CRP concentration 3-10 and > 10 mg/L, respectively) across pBMI and tGWG categories. RESULTS The mean pBMI, mean tGWG, and median maternal prepartum CRP concentration were 20.4 kg/m2, 13.9 kg, and 3.3 mg/L, respectively. The prevalence of prepartum CSI and LGI was 7.2% and 47.8%. The adjusted RRs (95% confidence interval) of CSI for normal (18.5-24.9 kg/m2) and high (≥ 25 kg/m2) vs. low pBMI (< 18.5 kg/m2) were 1.35 (1.05-1.74) and 2.28 (1.53-3.39), respectively. The respective adjusted RRs of LGI were 1.19 (1.11-1.28) and 1.59 (1.42-1.77). The adjusted RRs for excessive vs. optimal tGWG was 1.18 (0.94-1.48) for CSI and 1.14 (1.07-1.21) for LGI. CONCLUSIONS Prepregnancy overweight/obesity and excessive tGWG increase the risk of maternal prepartum systemic inflammation, which further highlights the importance of weight management before and during pregnancy.

Abstract
OBJECTIVE To examine the association of long-term weight change with RA risk in a large prospective cohort study. METHODS The Nurses' Health Study II started in 1989 (baseline); after exclusions, we studied 108 505 women 25-42 years old without RA. Incident RA was reported by participants and confirmed by medical record review. Body weight was reported biennially through 2015. We investigated two time-varying exposures: weight changes from baseline and from age 18; change was divided into five categories. We used a marginal structural model approach to account for time-varying weight change and covariates. RESULTS Over 2 583 266 person-years, with a median follow-up time of 25.3 years, 541 women developed RA. Compared with women with stable weight from baseline, weight change was significantly associated with increased RA risk [weight gain 2-<10 kg: RR = 1.98 (95% CI 1.38, 2.85); 10-<20 kg: RR = 3.28 (95% CI 2.20, 4.89); ≥20 kg: RR = 3.81 (95% CI 2.39, 6.07); and weight loss >2 kg: RR = 2.05 (95% CI 1.28, 3.28)]. Weight gain of 10 kg or more from age 18 compared with stable weight was also associated with increased RA risk [10-< 20 kg: RR = 2.12 (95% CI 1.37, 3.27), ≥20 kg: RR = 2.31 (95% CI 1.50, 3.56)]. Consistent findings were observed for seropositive and seronegative RA. CONCLUSION Long-term weight gain was strongly associated with increased RA risk in women, with weight gain of ≥20 kg associated with more than a three-fold increased RA risk. Maintenance of healthy weight may be a strategy to prevent or delay RA.

Int J Obes (Lond) 2022; 46:1234-1240. [PMID: 35260816 PMCID: PMC9151385 DOI: 10.1038/s41366-022-01101-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Revised: 02/08/2022] [Accepted: 02/15/2022] [Indexed: 11/30/2022]
Abstract
Background Obesity is associated with low-grade systemic inflammation, and it has been suggested that increased inflammation markers could predict future weight gain. Our aim was to investigate the associations of high-sensitivity C-reactive protein (hs-CRP) concentration with changes in weight and waist circumference in adults during 11 years of follow-up. Methods We used data from the Health 2000 and Health 2011 surveys consisting of a population-based sample of Finnish adults. We included those 3143 participants, aged 30–75 years at baseline, whose baseline hs-CRP was measured, and who had information on measured weight and height at both time points. Associations between baseline hs-CRP and changes in weight and waist circumference were analyzed using multinomial logistic regression, adjusted for sociodemographic factors (age, sex, marital status, and educational status), lifestyle factors (smoking, alcohol consumption, leisure-time physical activity, sitting time, sleeping time, and psychological distress), and baseline values of BMI and waist circumference. Results Hs-CRP was not associated with weight gain (≥5%) when adjusted for potential confounders (OR 0.99, 95% CI 0.96–1.01), compared to stable weight (change <±5%). Higher baseline hs-CRP was associated with decrease in weight (≤−5%) in the unadjusted (OR 1.03, 1.01–1.05), but not in the adjusted (OR 1.01, 0.99–1.03) model. No association was observed between hs-CRP and waist circumference. Conclusions Hs-CRP was not associated with future changes in weight or waist circumference in adults. These findings suggest that hs-CRP concentration does not predict future weight gain.

Abstract
INTRODUCTION To examine the independent association of body mass index (BMI) in early adulthood with dementia incidence among men and women. METHODS We studied 5104 older adults from the Cardiovascular Health Study (CHS) and the Health, Aging, and Body Composition (Health ABC) study. We imputed early adulthood and midlife BMI using a pooled parent cohort with complete adult lifespan coverage and previously established methods. Dementia was ascertained using criteria such as neuropsychological test battery, medical records, and dementia-related drug use. Pooled logistic regression (PLR) models were used. RESULTS Compared to women with normal BMI in early adulthood, the odds of dementia were higher among both overweight (odds ratio [OR] = 1.8; 95% confidence interval [CI] = 1.31 to 2.54) and obese (OR = 2.45; 95% CI = 1.47 to 4.06) women, independent of mid- and late-life BMI. Similar relationship was observed in men. CONCLUSIONS With the growing obesity epidemic among US adults, efforts aimed at reducing dementia may need to begin obesity prevention and treatment early in the life course.

Adiposity and pathogen exposure: An investigation of response to iron supplementation and hypothesized predictors in anemic pre-school-aged children living in a dual burden environment.

Abstract
OBJECTIVES Peruvians are experiencing rapid dietary and lifestyle changes, resulting in a phenomenon known as the "dual burden of disease." A common manifestation of the dual burden in individuals is the co-occurrence of overweight and anemia. Despite recent initiatives introduced to address these concerns, rates continue to be public health concerns. This study investigates the relationship between immune activation and lack of response to iron supplementation after 1 month of treatment and explores variation in body fat stores as a potential moderator between immune function and response to treatment. METHODS Data come from children, aged 2-5 years (n = 50) from a peri-urban community in Lima, Peru. Multivariate logistic regression models were used to explore the associations between response to treatment (Hb > =11.0 g/dl) after 1 month of treatment), markers of immune activation (C-reactive protein [CRP] and reported morbidity symptoms), and measures of body fat (waist-to-height ratio, triceps skinfold thickness, and body mass index [BMI]). RESULTS We found that high CRP is associated with a lack of response to iron supplementation after 1 month of treatment and that BMI z-score may moderate this association. Generally, larger body size is associated with response to iron supplementation whether or not the children in this sample have high immune activation. However, the probability of anemic children responding to iron supplementation treatment differed across adiposity measures. CONCLUSIONS Our finding suggesting that adiposity and CRP influence response to iron supplementation, furthers our understanding of the relationship between inflammation and anemia treatment in children and has both theoretical and public health implications.

Abstract
BACKGROUND Mood disorders and adiposity are major public health challenges. Few studies have investigated the bidirectional association of weight and waist circumference (WC) change with psychological distress in middle age, while taking into account the potential U-shape of the association. The aim of this study was to examine the bidirectional association between psychological distress and categorical change in objectively measured weight and WC. METHODS We analysed repeated measures (up to 17 522 person-observations in adjusted analyses) of psychological distress, weight and WC from the Whitehall II cohort. Participants were recruited at age 35-55 and 67% male. Psychological distress was assessed using the General Health Questionnaire. We used random-effects regressions to model the association between weight and WC changes and psychological distress, with and without a 5-year lag period. RESULTS Psychological distress was associated with weight and WC gain over the subsequent 5 years but not the second 5-year period. Weight gain and loss were associated with increased odds for incident psychological distress in models with and without time-lag [odds ratio (OR) for incident psychological distress after 5-year time-lag: loss 1.20, 95% confidence interval (CI) 1.00-1.43; gain>5% 1.20, 95% CI 1.02-1.40]. WC changes were only associated with psychological distress in models without time-lag (OR for incident psychological distress: loss 1.29, 95% CI 1.02-1.64; gain>5% 1.33, 95% CI 1.11-1.58). CONCLUSIONS Weight gain and loss increase the odds for psychological distress compared with stable weight over subsequent 10 years. In contrast, the association between psychological distress and subsequent weight and WC changes was limited to the first 5 years of follow-up.

Abstract
BACKGROUND AND AIMS Longitudinal studies relating adiposity with low-grade inflammation are scarce. We aimed to examine the longitudinal association between the cumulative exposure to adiposity and low-grade inflammation from adolescence into early adulthood. METHODS AND RESULTS Data from a population-based cohort (EPITeen) (n = 1147) was analyzed. Body mass index (BMI), body fat percentage (BF%), waist circumference (WC), and waist-to-height ratio (WHtR) and high-sensitivity C-reactive protein (hsCRP) were ascertained at 13, 17 and 21 years of age and standardized for each wave. Generalized least squares models with a compound symmetry correlation structure were fitted to estimate the longitudinal effect of adiposity on hsCRP and results were presented as linear regression coefficients and 95% confidence intervals [β (95%CI)].The final model estimated the association between the difference in adiposity between two consecutive evaluations (13-17 and 17 to 21-years-old), adjusted for previous adiposity and hsCRP levels, sex, parental education, leisure-time physical activity and fruits and vegetables intake. A positive association between the cumulative exposure to adiposity and final hsCRP was observed, in which the difference between adiposity indicators of two consecutive study waves was independently associated with hsCRP: 0.382 (0.299; 0.465) for BMI, 0.234 (0.164; 0.304) for WC, 0.395 (0.314; 0.477) for BF% and 0.195 (0.133; 0.258) for WHtR. CONCLUSION A significant longitudinal effect of the accumulation of adiposity on low-grade inflammation was observed. The change in adiposity from consecutive study waves was shown to have a stronger effect on final hsCRP concentrations than both previous adiposity and hsCRP levels.

Abstract
PURPOSE The aim of the present study was to derive overall and sex-specific dietary patterns associated with inflammatory biomarkers in a general population sample from Northern Germany. METHODS The present analysis included 1158 participants (477 men, 681 women, mean age: 53.1 years; mean body mass index: 26.2 kg/m2) of the Food Chain Plus (FoCus) cohort in Kiel, Germany. Participants completed a semi-quantitative food frequency questionnaire and provided blood samples. Reduced rank regression with C-reactive protein (CRP) and Interleukin 6 (IL-6) as response variables was used to derive dietary patterns. After a mean follow-up of 1.7 years, a second blood sample was obtained in a subsample of 112 individuals. Multiple regression models were used to examine the association between dietary patterns at baseline and inflammatory biomarkers at follow-up. RESULTS The overall pattern characterised by high intakes of soft drinks, meat, potatoes and sauce, and low intakes of other cereals (except pasta/rice), wine, nuts, seeds, vegetarian dishes, vegetable oil, and fish was positively associated with CRP (OR 2.20; 95% CI 1.12, 4.35) and IL-6 (OR 3.14; 95% CI 1.26, 7.87) at follow-up. In men, the dietary pattern was higher in soft drinks, processed meat and low in cereals and plant-based fats. In women, the pattern was characterised by soft drinks, meat, vegetables and low in other cereals, wine, nuts, and seeds. The association between sex-specific patterns with inflammatory biomarkers was weaker for CRP. CONCLUSION We identified dietary patterns positively associated with established biomarkers of chronic low-grade inflammation.

Abstract
OBJECTIVES In two cohorts, we aimed to establish associations between early-life adversities and adult inflammation, and whether adult (a) adiposity or (b) socioeconomic disadvantage are key intermediaries. METHODS In both cohorts (N = 7661, 1958 British birth cohort; N = 1255, MIDUS), information was used on adult inflammatory markers (C-reactive protein (CRP), fibrinogen and (MIDUS only) interleukin-6 (IL-6)), adiposity and socioeconomic disadvantage, and early-life adversities (neglect, emotional neglect, physical, psychological, sexual abuse and childhood disadvantage). RESULTS Early-life adversities varied from 1.6% (sexual abuse, 1958 cohort) to 14.3% (socioeconomic disadvantage, MIDUS). Across the two cohorts, associations were consistent for physical abuse, e.g. 16.3%(3.01,29.7) and 17.0%(-16.4,50.3) higher CRP in the 1958 cohort and MIDUS respectively. Associations attenuated after accounting for adult adiposity, e.g. physical abuse (1958 cohort) and sexual abuse (MIDUS, non-white participants) associations were abolished. Some associations attenuated after adjustment for adult socioeconomic disadvantage; e.g. 1958 cohort neglect-CRP associations reduced from 23.2%(13.7,32.6) to 17.7%(8.18,27.2). Across the cohorts, no associations were found for psychological abuse or emotional neglect; associations for childhood socioeconomic disadvantage were inconsistent. CONCLUSIONS Specific early-life adversities are associated with adult inflammation; adiposity is a likely intermediary factor. Weight reduction and obesity prevention may offset pro-inflammatory related adult disease among those who experienced early-life adversities.

Abstract
Osteoarthritis (OA) is a leading cause of immobility in the United States and is associated with older age, inflammation, and obesity. Prudent dietary patterns have been associated with disease prevention, yet little evidence exists describing diet quality (DQ) in older overweight or obese African American (AA) adults with OA and its relation to body composition. We conducted a secondary data analysis of a dataset containing alternate Healthy Eating Index-2010 (AHEI-2010), body composition, OA severity, and serum interleukin-6 (IL-6) data from 126 AA females (aged 60–87 years) with OA to examine the relationships between these variables. Our sample had poor DQ and reported having higher OA severity as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Interleukin-6 was negatively correlated with AHEI-2010, and AHEI-2010 and the WOMAC physical function subcategory (WOMACpf) were significant predictors of IL-6 (odds ratio (OR): 0.95, 95% confidence interval (CI) 0.92–0.99 and 1.04, 95% CI 1.01–1.07, respectively, p < 0.05) but not body composition. In conclusion, AHEI-2010 and WOMACpf were significant predictors of inflammation (IL-6) and AHEI-2010 accounted for ~16% of the variation of IL-6 (inflammation) in this sample.

Abstract
Siloed or singular system approach to disease management is common practice, developing out of traditional medical school education. Textbooks of medicine describe a huge number of discrete diseases, usually in a systematic fashion following headings like etiology, pathology, investigations, differential diagnoses, and management. This approach suggests that the body has a multitude of ways to respond to harmful incidences. However, physiology and systems biology provide evidence that there is a simple mechanism behind this phenotypical variability. Regardless if an injury or change was caused by trauma, infection, non-communicable disease, autoimmune disorders, or stress, the typical physiological response is: an increase in blood supply to the area, an increase in white cells into the affected tissue, an increase in phagocytic activity to remove the offending agent, followed by a down-regulation of these mechanisms resulting in healing. The cascade of inflammation is the body's unique mechanism to maintain its integrity in response to macroscopic as well as microscopic injuries. We hypothesize that chronic disease development and progression are linked to uncontrolled or dysfunctional inflammation to injuries regardless of their nature, physical, environmental, or psychological. Thus, we aim to reframe the prevailing approach of management of individual diseases into a more integrated systemic approach of treating the "person as a whole," enhancing the patient experience, ability to a make necessary changes, and maximize overall health and well-being. The first part of the paper reviews the local immune cascades of pro- and anti-inflammatory regulation and the interconnected feedback loops with neural and psychological pathways. The second part emphasizes one of nature's principles at work-system design and efficiency. Continually overwhelming this finely tuned system will result in systemic inflammation allowing chronic diseases to emerge; the pathways of several common conditions are described in detail. The final part of the paper considers the implications of these understandings for clinical care and explore how this lens could shape the physician-patient encounter and health system redesign. We conclude that healthcare professionals must advocate for an anti-inflammatory lifestyle at the patient level as well as at the local and national levels to enhance population health and well-being.

Abstract
OBJECTIVE Limited studies have assessed the relationship between longitudinal changes in adiposity and changes in multiple adipokines over time. This study examined changes in BMI, total body fat, and trunk fat associated with changes in 16 circulating adipokines in Mexican Americans at risk for type 2 diabetes. METHODS Participants included 1,213 individuals with cross-sectional data and a subset of 368 individuals with follow-up measures (mean 4.6 ± 1.5 years from baseline). Joint multivariate associations between 3 adiposity measures and 16 adipokines were assessed by canonical correlation analysis. RESULTS Longitudinal increases in adiposity were most strongly associated with increasing leptin, C-reactive protein (CRP), and interleukin 1 receptor antagonist (IL-1Ra) and decreasing adiponectin and secreted frizzled protein 5 (SFRP5) over time. Participants with BMI ≥ 30 kg/m2 at baseline had greater increases in leptin, CRP, IL-1Ra, and interleukin 6 (IL-6) and greater decreases in adiponectin and SFRP5, associated with increasing adiposity over follow-up, than those with BMI < 30 kg/m2 . Associations between adiposity and adipokines were most accounted for by leptin; adjustment for leptin greatly reduced the magnitude of all associations between adiposity and remaining adipokines. CONCLUSIONS Increasing adiposity contributes to a worsening imbalance of pro- and anti-inflammatory adipokines over time, in which leptin may have an important role as a key mediator of metabolic disease risk in Mexican Americans.

Abstract
BACKGROUND Recent longitudinal work suggests that weight change is an important risk factor for inflammation across the full range of BMI. However, few studies have examined whether the risk of inflammation differs by patterns of weight gain over time. Using latent class trajectory analysis, we test whether patterns of weight gain are associated with elevated high-sensitivity C-reactive protein (hs-CRP 2-10 mg/L). METHODS AND RESULTS Data come from China Health and Nutrition Survey (CHNS) participants (n=5536), aged 18 at baseline to 66 years in 2009, with measured weight over 18 years. Latent class trajectory analysis was used to identify weight-change trajectories in 6 age and sex strata. Multivariable general linear mixed-effects models fit with a logit link were used to assess the risk of elevated hs-CRP across weight trajectory classes. Models were fit within age and sex strata, controlling for baseline weight, adult height, and smoking, and included random intercepts to account for community-level correlation. Steeper weight-gain trajectories were associated with greater risk of elevated hs-CRP compared to more moderate weight-gain trajectories in men and women. Initially high weight gain followed by weight loss was associated with lower risk of elevated hs-CRP in women aged 18 to 40. CONCLUSIONS Latent class trajectory analysis identified heterogeneity in adult weight change associated with differential risk of inflammation independently of baseline weight and smoking. These results suggest that trajectories of weight gain are an important clinical concern and may identify those at risk for inflammation and the development of cardiometabolic disease.

Abstract
The proportion of overweight and obese adults in the United States and Canada has increased over the past decade, but temporal trends in body mass index (BMI) and weight gain on antiretroviral therapy (ART) among HIV-infected adults have not been well characterized. We conducted a cohort study comparing HIV-infected adults in the North America AIDS Cohort Collaboration on Research and Design (NA-ACCORD) to United States National Health and Nutrition Examination Survey (NHANES) controls matched by sex, race, and age over the period 1998 to 2010. Multivariable linear regression assessed the relationship between BMI and year of ART initiation, adjusting for sex, race, age, and baseline CD4(+) count. Temporal trends in weight on ART were assessed using a generalized least-squares model further adjusted for HIV-1 RNA and first ART regimen class. A total of 14,084 patients from 17 cohorts contributed data; 83% were male, 57% were nonwhite, and the median age was 40 years. Median BMI at ART initiation increased from 23.8 to 24.8 kg/m(2) between 1998 and 2010 in NA-ACCORD, but the percentage of those obese (BMI ≥30 kg/m(2)) at ART initiation increased from 9% to 18%. After 3 years of ART, 22% of individuals with a normal BMI (18.5-24.9 kg/m(2)) at baseline had become overweight (BMI 25.0-29.9 kg/m(2)), and 18% of those overweight at baseline had become obese. HIV-infected white women had a higher BMI after 3 years of ART as compared to age-matched white women in NHANES (p = 0.02), while no difference in BMI after 3 years of ART was observed for HIV-infected men or non-white women compared to controls. The high prevalence of obesity we observed among ART-exposed HIV-infected adults in North America may contribute to health complications in the future.

Demeestere D, Libert C, Vandenbroucke RE. Therapeutic implications of the choroid plexus-cerebrospinal fluid interface in neuropsychiatric disorders. Brain Behav Immun 2015; 50:1-13. [PMID: 26116435 DOI: 10.1016/j.bbi.2015.06.010] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2015] [Revised: 05/29/2015] [Accepted: 06/13/2015] [Indexed: 12/31/2022] Open
Abstract
The choroid plexus (CP) comprises an epithelial monolayer that forms an important physical, enzymatic and immunologic barrier, called the blood-cerebrospinal fluid barrier (BCSFB). It is a highly vascularized organ located in the brain ventricles that is key in maintaining brain homeostasis as it produces cerebrospinal fluid (CSF) and has other important secretory functions. Furthermore, the CP-CSF interface plays a putative role in neurogenesis and has been implicated in neuropsychiatric diseases such as the neurodevelopmental disorders schizophrenia and autism. A role for this CNS border was also implicated in sleep disturbances and chronic and/or severe stress, which are risk factors for the development of neuropsychiatric conditions. Understanding the mechanisms by which disturbance of the homeostasis at the CP-CSF interface is involved in these different chronic low-grade inflammatory diseases can give new insights into therapeutic strategies. Hence, this review discusses the different roles that have been suggested so far for the CP in these neuropsychiatric disorders, with special attention to potential therapeutic applications.

Abstract
PURPOSE Many dietary factors have either proinflammatory or anti-inflammatory properties. We previously developed a dietary inflammatory index (DII) to assess the inflammatory potential of diet. In this study, we conducted a construct validation of the DII based on data from a food frequency questionnaire and three inflammatory biomarkers in a subsample of 2567 postmenopausal women in the Women's Health Initiative Observational Study. METHODS We used multiple linear and logistic regression models, controlling for potential confounders, to test whether baseline DII predicted concentrations of interleukin-6, high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor alpha receptor 2, or an overall biomarker score combining all three inflammatory biomarkers. RESULTS The DII was associated with the four biomarkers with beta estimates (95% confidence interval) comparing the highest with lowest DII quintiles as follows: interleukin-6: 1.26 (1.15-1.38), Ptrend < .0001; tumor necrosis factor alpha receptor 2: 81.43 (19.15-143.71), Ptrend = .004; dichotomized hs-CRP (odds ratio for higher vs. lower hs-CRP): 1.30 (0.97-1.67), Ptrend = .34; and the combined inflammatory biomarker score: 0.26 (0.12-0.40), Ptrend = .0001. CONCLUSIONS The DII was significantly associated with inflammatory biomarkers. Construct validity of the DII indicates its utility for assessing the inflammatory potential of diet and for expanding its use to include associations with common chronic diseases in future studies.

Abstract
BACKGROUND The environmental and behavioral risk factors associated with central obesity and/or inflammation in populations exposed to both obesogenic and pathogenic environments remain unclear. OBJECTIVES We tested which of the characteristics distinguished 3 risk groups--high waist-to-height ratio (WHtR; >0.5) without inflammation [high-sensitivity C-reactive protein (hs-CRP) <3 mg/L], normal WHtR (≤ 0.5) with inflammation (hs-CRP: 3-10 mg/L), and high WHtR with inflammation--from the referent group with normal WHtR without inflammation and, secondarily, which factors differed between the groups with high WHtR with and without inflammation. METHODS The analytic sample included 8068 adults participating in the China Health and Nutrition Survey in 2009. Adjusted multinomial and logistic regression models were used to assess the risk of being in one of the "unhealthy" groups compared with the referent group. RESULTS Men with high WHtR with and without inflammation were more likely to live at higher urbanicity (57-63%) and have higher incomes (26-42%) and household sanitation (26-67%) and were >40% less likely to have high physical activity than the healthy referent group. Men with high WHtR with inflammation had higher odds of infectious symptoms than those with high WHtR without inflammation (OR: 1.73; 95% CI: 1.15, 2.61). Women with high WHtR without inflammation were less likely to have high household sanitation (44%) or perform high levels of physical activity (24%) and were 34% more likely to consume more fiber than the healthy referent group. Women with high WHtR and inflammation were more likely than those with high WHtR without inflammation to have infectious symptoms (OR: 1.45; 95% CI: 1.01, 2.07) and less likely to have higher fiber intake (OR: 0.77; 95% CI: 0.60,1.00) or physical activity (OR: 0.55; 95% CI: 0.41, 0.73). CONCLUSION These results document different underlying pathogenic and obesogenic risk factors for visceral adiposity with and without inflammation in Chinese adults, suggesting that context-specific approaches may be needed to prevent and treat inflammation.

Abstract
Self-reported discrimination has emerged as a predictor of negative psychological and physical health outcomes across racial/ethnic groups. The goals of this study were to determine whether C-reactive protein (CRP), a marker of inflammation and risk factor for future cardiovascular disease (CVD) was independently predicted by everyday discrimination or whether race or body mass index (BMI) modified this association over a 7-year period among 2,490 women from racially diverse backgrounds. At baseline, the 10-item Williams' measure of everyday discrimination was administered. Generalized estimating equations were used to assess these associations. Descriptive results showed that Black and Chinese women reported greater discrimination than White, Japanese, and Hispanic women, while Black and Hispanic women had the highest levels of CRP over the 7-year period. There was no main effect of everyday discrimination (B = .003, SE = .005, p = .58) and this association did not differ as a function of race (p's > .05). The everyday discrimination × BMI interaction term significantly predicted higher CRP levels over time in the full sample of women (p = .03). Specifically, in non-obese women (BMI less than 30), higher perceived everyday discrimination was associated with higher CRP levels over the 7-year period. These findings were independent of demographic, negative affect, biomedical, and behavioral factors. The results demonstrate that greater everyday discrimination is associated with increased inflammation over time in non-obese women. These findings highlight the implications of interpersonal sources of social stress for long-term physical health via their impact on intermediary biological pathways, specifically inflammation. Greater emphasis on such linkages is warranted as we work towards ameliorating health disparities exacerbated by individual-level factors.

Abstract
PURPOSE C-reactive protein (CRP), an inflammation marker, is associated with colorectal cancer (CRC) risk in some prospective studies. Whether increased CRP is indicative of colonic inflammation, a possible CRC cause, or of other sources of inflammation (e.g., adiposity), is unknown. Thus, we evaluated the association between CRP and colonic mucosal measures of inflammation. METHODS 151 adults undergoing colonoscopy provided a blood sample and random left- and right-side colonic mucosal biopsies. Height and weight were measured, and lifestyle information was collected. High-sensitivity C-reactive protein (hsCRP) was measured by immunoturbidometric assay. A gastrointestinal pathologist evaluated biopsies for seven colonic inflammation measures. Of 119 participants with complete information, 24 had an inflammatory bowel disease (IBD) history and were analyzed separately. We calculated the number of colonic inflammation measures present in both biopsies, and separately for right and left biopsies. Adjusted geometric mean hsCRP was calculated using linear regression, overall, by demographic and lifestyle factors, and inflammation measures. RESULTS Most participants had ≥ 1 colonic inflammation measure (0: 21 %, 1: 39 %, ≥ 2: 40 %). Adjusted mean hsCRP did not increase with increasing number of inflammation measures (0: 1.67; 1: 1.33; ≥ 2: 1.01 mg/L; p trend = 0.21). Obese (2.03 mg/L) and overweight (1.61 mg/L) participants had higher adjusted mean hsCRP than normal-weight participants (0.62 mg/L; p trend <0.0001). Patterns were similar for participants with a history of IBD. CONCLUSIONS hsCRP concentration was not associated with colonic inflammation, although hsCRP increased with adiposity. The hsCRP-CRC association may be explained by residual confounding by other risk factors, such as adiposity, rather than by CRP marking colonic inflammation.

Abstract
OBJECTIVE Obesity is an underrecognized risk factor for rheumatoid arthritis (RA). In recent years, both the prevalence of obesity and the incidence of RA have been rising. Our objective was to determine whether the "obesity epidemic" could explain the recent rise in the incidence of RA. METHODS An inception cohort of Olmsted County, Minnesota residents who fulfilled the 1987 American College of Rheumatology criteria for RA in 1980-2007 was compared to population-based controls (matched on age, sex, and calendar year). Heights, weights, and smoking statuses were collected from medical records. Obesity was defined as a body mass index ≥30 kg/m(2) . Conditional logistic regression was used to assess the influence of obesity on developing RA. Population attributable risk was used to estimate the incidence of RA in the absence of obesity. RESULTS The study included 813 patients with RA and 813 controls. Both groups had extensive medical history available prior to the incidence/index date (mean 32.2 years), and ~30% of each group was obese at the incidence/index date. The history of obesity was significantly associated with developing RA (odds ratio 1.24, 95% confidence interval 1.01-1.53; adjusted for smoking status). In 1985-2007, the incidence of RA rose by an increment of 9.2 per 100,000 among women. Obesity accounted for 4.8 per 100,000 (52%) of this increase. CONCLUSION Obesity is associated with a modest risk for developing RA. Given the rapidly increasing prevalence of obesity, this has had a significant impact on RA incidence and may account for much of the recent increase in the incidence of RA.

Abstract
PURPOSE This study investigated the association between weight change and inflammation in a nationally representative population of US adults aged 40 and older. METHODS Using the US National Health and Nutrition Examination Survey (2005-2008), logistic regression models were used to determine the relationship between high levels of inflammation (C-reactive protein [CRP]) and infection (white blood cell count [WBC]) with 1- and 10-year change in self-reported weight status. RESULTS Change in 1- and 10-year weight was associated with high CRP but not high WBC. Individuals who gained or lost ≥10 kg had an odds of having high CRP that was 1.96 (95% CI 1.11-3.50) and 1.61 (95% CI 1.02-2.46) as high, respectively, as those who maintained a stable weight (<4 kg change) in the past year. The increased risk of elevated CRP among individuals who experienced at least 10 kg of weight loss or weight gain was also observed for weight change that occurred over the past 10 years; however, weight loss over the 10-year period was no longer associated with high inflammation. CONCLUSIONS These results suggest that adult respondents who retrospectively self-reported weight loss or gain had higher levels of inflammation relative to their weight stable counterparts.

Abstract
BACKGROUND Inflammatory processes are putative mechanisms underlying the cardioprotective effects of physical activity. An inverse association between physical activity and inflammation has been demonstrated, but no long-term prospective data are available. We therefore examined the association between physical activity and inflammatory markers over a 10-year follow-up period. METHODS AND RESULTS Participants were 4289 men and women (mean age, 49.2 years) from the Whitehall II cohort study. Self-reported physical activity and inflammatory markers (serum high-sensitivity C-reactive protein and interleukin-6) were measured at baseline (1991) and follow-up (2002). Forty-nine percent of the participants adhered to standard physical activity recommendations for cardiovascular health (2.5 h/wk moderate to vigorous physical activity) across all assessments. Physically active participants at baseline had lower C-reactive protein and interleukin-6 levels, and this difference remained stable over time. Compared with participants who rarely adhered to physical activity guidelines over the 10-year follow-up, the high-adherence group displayed lower log(e) C-reactive protein (β=-0.07; 95% confidence interval, -0.12 to -0.02) and log(e) interleukin-6 (β=-0.07; 95% confidence interval, -0.10 to -0.03) at follow-up after adjustment for a range of covariates. Compared with participants who remained stable, those who reported an increase in physical activity of at least 2.5 h/wk displayed lower log(e) C-reactive protein (β coefficient=-0.05; 95% confidence interval, -0.10 to -0.001) and log(e) interleukin-6 (β coefficient=-0.06; 95% confidence interval, -0.09 to -0.03) at follow-up. CONCLUSIONS Regular physical activity is associated with lower markers of inflammation over 10 years of follow-up and thus may be important in preventing the proinflammatory state seen with aging.

Abstract
PURPOSE To investigate whether cellular imaging by using ultrasmall superparamagnetic iron oxide (USPIO)-enhanced magnetic resonance (MR) imaging can allow detection and quantification of adipose tissue macrophage-related inflammation within adipose tissue in a mouse model. MATERIALS AND METHODS Experimental protocols were conducted in accordance with French government policies. Adipose tissue macrophages were detected and quantified with a 4.7-T MR imager in ob/ob obese mice on the basis of the signal variance of adipose tissue triggered by injection of P904 iron oxide nanoparticles (USPIO). Mice were either intravenously injected with 1000 μmol of iron per kilogram of body weight of P904 (10 ob/ob and 11 ob/+) or used as noninjected control animals (seven ob/ob and six ob/+). Three-dimensional T2*-weighted gradient-echo MR images were acquired 10 days after intravenous injection. MR imaging signal variance in mice was correlated to adipose tissue macrophage quantification by using monoclonal antibody to F4/80 immunostaining, to proinflammatory marker quantification by using reverse transcription polymerase chain reaction (CCl2, Tnfα, Emr1), and to P904 quantification by using electron paramagnetic resonance imaging. Quantitative data were compared by using the Mann-Whitney or Student t test, and correlations were performed by using the Pearson correlation test. RESULTS MR imaging measurements showed a significant increase in adipose tissue signal variance in ob/ob mice compared with ob/+ controls or noninjected animals (P < .0001), which was consistent with increased P904 uptake by adipose tissue in ob/ob mice. There was a significant and positive correlation between adipose tissue macrophage quantification at MR imaging and P904 iron oxide content (r = 0.87, P < .0001), adipose tissue macrophage-related inflammation at immunohistochemistry (r = 0.60, P < .01), and adipose tissue proinflammatory marker expression (r = 0.55, 0.56, and 0.58 for CCl2, Tnfα, and Emr1, respectively; P < .01). CONCLUSION P904 USPIO-enhanced MR imaging is potentially a tool for noninvasive assessment of adipose tissue inflammation during experimental obesity. These results provide the basis for translation of MR imaging into clinical practice as a marker of patients at risk for metabolic syndrome.

Abstract
Background: Mechanisms underlying coffee's beneficial actions against cardiovascular disease and glucose metabolism are not well understood. Little information is available regarding association between coffee consumption and adipocytokines. Objective: We investigated potential associations between coffee consumption and adiponectin, leptin, markers for subclinical inflammation, glucose metabolism, lipids and liver enzymes. We then investigated whether adipocytokines played a role in the association between coffee consumption and these markers. Design and subjects: This is a cross-sectional study comprising 2554 male and 763 female Japanese workers. Potential relations between coffee consumption and adipocytokines or other markers were evaluated using a multiple linear regression model adjusted for confounding factors. We evaluated whether adiponectin and leptin partly explain the associations between coffee consumption and each marker by multiple mediation analysis. Results: Coffee consumption showed significant positive associations with adiponectin and total and low-density lipoprotein cholesterol, and inverse associations with leptin, high sensitivity C-reactive protein (hs-CRP), triglycerides and liver enzymes (all P<0.05). An adjustment for adiponectin and leptin significantly attenuated the associations between coffee consumption and hs-CRP or triglycerides, but not for liver enzymes. No associations were observed between coffee consumption and glucose metabolism-related markers. Conclusion: Coffee consumption was associated with high adiponectin and low leptin levels. We speculated that adipocytokines mainly explain the associations of coffee consumption with lipids and hs-CRP. Factors other than adipocytokines may explain the association between coffee consumption and liver function.

Abstract
BACKGROUND For the elderly, the association between waist circumference (WC) and mortality considering body mass index (BMI) remains unclear, and thereby also the evidence base for using these anthropometric measures in clinical practice. This meta-analysis examined the association between WC categories and (cause-specific) mortality within BMI categories. Furthermore, the association of continuous WC with lowest and increased mortality risks was examined. METHODS Age- and smoking-adjusted relative risks (RRs) of mortality associated with WC-BMI categories and continuous WC (including WC and WC(2)) were calculated by the investigators and pooled by means of random-effects models. RESULTS During a 5-year-follow-up of 32 678 men and 25 931 women, we ascertained 3318 and 1480 deaths, respectively. A large WC (men: ≥102 cm, women: ≥88 cm) was associated with increased all-cause mortality RRs for those in the 'healthy' weight {1.7 [95% confidence interval (CI): 1.2-2.2], 1.7 (95% CI: 1.3-2.3)}, overweight [1.1(95% CI: 1.0-1.3), 1.4 (95%: 1.1-1.7)] and obese [1.1 (95% CI: 1.0-1.3), 1.6 (95% CI: 1.3-1.9)] BMI category compared with the 'healthy' weight (20-24.9 kg/m(2)) and a small WC (<94 cm, men; <80 cm, women) category. Underweight was associated with highest all-cause mortality RRs in men [2.2 (95% CI: 1.8-2.8)] and women [2.3 (95% CI: 1.8-3.1]. We found a J-shaped association for continuous WC with all-cause, cardiovascular (CVD) and cancer, and a U-shaped association with respiratory disease mortality (P < 0.05). An all-cause (CVD) mortality RR of 2.0 was associated with a WC of 132 cm (123 cm) in men and 116 cm (105 cm) in women. CONCLUSIONS Our results showed increased mortality risks for elderly people with an increased WC-even across BMI categories- and for those who were classified as 'underweight' using BMI. The results provide a solid basis for re-evaluation of WC cut-points in ageing populations.

Abstract
BACKGROUND In dialysis patients, cross-sectional studies show that total and abdominal body fat associate with inflammatory markers. Whether this is true in earlier disease stages is unknown. We evaluated the cross-sectional and longitudinal (12-month interval) association between body fat markers and C-reactive protein (CRP) in pre-dialysis chronic kidney disease (CKD) patients. METHODS We studied, over a period of 1 year, clinically stable CKD patients at Stages 3-4 who were under treatment in a single outpatient clinic. Fifty-seven patients were included and 44 concluded the observational period [males: 66%; age: 62.9±13.9 years; body mass index (BMI): 25.5±5.1 kg/m2; estimated glomerular filtration rate (eGFR): 34±12.3 mL/min/1.73 m2]. Total body fat (skinfold thicknesses), waist circumference (WC), laboratory measurements (serum creatinine, total cholesterol, albumin, high-sensitivity CRP and leptin) and food intake (24-h food recall) were assessed at baseline and after 12±2 months. RESULTS Most patients had anthropometric parameters in the range of overweight/obesity and none had signs of protein-energy wasting. In univariate analysis, changes (delta: end-baseline) in CRP were associated (P<0.05) with changes in BMI (r=0.39) and WC (r=0.33). In multiple regression analysis, these associations remained significant (P<0.05) even after adjusted by potential confounders (sex, diabetes, baseline age and eGFR). CONCLUSIONS During a follow-up of 12 months, changes in BMI and WC were directly associated with changes in CRP. Our results support the concept that interventions aimed at reducing weight and/or abdominal adiposity in pre-dialysis CKD patients may also translate into reduced systemic inflammation.
